Calculation of thermodynamic calculation is the basis of the General the calculation of the compressor in heat-aided design systems have a compressor to help would greatly speed up the design process so that a more rational Compressor lubricating oil and has no thermodynamic calculation， the calculation in manual access map errors， data are not consistent with the calculation of the selected request， the result of incorrect calculations or At present there is no response to any oil-lubricated compressor-assisted calculation By the calculation of the required number of charts， prepared without oil lubricated compressor Thermodynamics-aided design system， simplifies the success of any oil-lubricated compressor thermodynamic calculation process， the realization of the data required to calculate the line selection， Chaturvedi smart look-up table， the output of data， save and print， and to improve the accuracy of the calculation parameters and Key words thermal calculation compressor oil-free-aided design system希望能帮到你
Pressure Vessel design of the chemical industry that is a kind of mechanical design， in order to meet the needs of social life， the constant pressure vessel development and In order to production needs， the structure of the pressure vessel， the design of the way， bringing them in line with customer demand factory， the design of the following: First， pressure vessels of the board of the design; two， shell hole size， location of the design; 3 ， Welding technology of This paper reviews the new type of highly efficient heat exchangers at home and abroad in recent years for the Research， Design and in accordance with national standards of shell-and-a heat exchanger， found problems in the design and through， choose the right parts， on the basis of knowledge of Shell heat exchanger to improve the views， but also at home and abroad enhanced heat transfer components and a new highly efficient heat transfer technology direction of development were Key words:（关键词：） mechanical design， heat exchangers， heat transfer enhancement， head， flange， Baffled， the national standard希望我的翻译对你有帮助
